Abstract

In an improved method and system for decreasing the user-perceived system response time when accessing web sites, the server is configured to service the initial web page request and then identify a set of N web site elements which are likely to be subsequently requested by the client. This set of resources is then streamed to the client. When the server determines that the client has accessed a sufficient number of the streamed elements or reached another threshold, a subsequent set of N site elements is identified and streamed to the server.

Claims

1. A method of streaming web site elements from a server to a client comprising the steps of:

receiving an initial request for an element from a client;

sending the requested element to the client;

identifying a first set of N web site elements which can be requested by the client;

streaming the initial set of N elements to the client;

upon a determination that the client has accessed M of the N streamed elements, M<

=N, identifying a second set of N web site elements which can be requested by the client and streaming the second set of N elements to the client.

2. The method of

claim 1

streaming the subsequent set of N elements to the client.

5. The method of

claim 4

, wherein the subsequent set of N elements is streamed to the client prior to other elements selected for streaming to the client but not streamed.
